Veteran British guitar band Wishbone Ash is set to play the Aztec Theatre on May 1 , while soulful jack of all trades Boz Scaggs will play the Tobin Center on May 4. Coincidentally, those two shared a bill at Laurie Auditorium way back in the fall of 1972; Scaggs was the headliner.

Here’s the surreal part: I was at that show, and was remembering it after the Wishbone Ash concert announcement landed in my inbox. Moments later came the news release on the Scaggs show. Cue the “Twilight Zone” theme.

That long-ago bill was not an ideal pairing. A freshman at UT-Austin, I came down to San Antonio specifically to see Wishbone Ash because I loved their 1972 album “Argus.” This was back before Austin became the musical capital of the world and San Antonio often had better rock shows.

But their blues-rocking, twin-guitar act didn’t meld real well with Scaggs, who was beginning to mellow into his “Lowdown” phase and didn’t take kindly to shouted requests for his older, heavier stuff (“Wanna boogie?,” he said sarcastically, scraping his Gibson Les Paul).

Anyway, lesson learned: Don’t go for the opening act.

Scaggs, a Texas native who first made his mark with the Steve Miller Band, has since added to an impressive, eclectic resume. He’ll be touring in support of “A Fool to Care,” which will be released March 31. Recorded in a four-day span in Nashville, it draws from the music of his home state as well as Oklahoma and Louisiana, he indicated in a news release. Guests on the album include Bonnie Raitt and Lucinda Williams.

Wishbone Ash, despite a revolving door in the personnel department, is still anchored by founding guitarist Andy Powell. The band’s set list will span its 46-year career as well as featuring its latest album, “Blue Horizon.”

Powell, know for his trademark Gibson Flying-V guitar, recently won a legal battle concerning the band name with former bandmate Martin Turner, who had been performing as “Martin Turner’s Wishbone Ash” and had even re-recorded “Argus.” A London court in 2014 found for Powell; Turner now performs as “Martin Turner plays the music of Wishbone Ash.”

Nice to know on the upcoming tour, Powell won’t have to compete with another Wishbone Ash. Or play second banana to Scaggs again.
